WINDOW 0R THE LIKE.

Application led March 17, 1920. Serial No. 366,654.

To all whom t may concern:

Be it known that I, ARTHUR WATKINSON, a subject of the King of England, residing at Willesden, London, N. IV., England, have invented certain new and useful Improvements in Windows or the like, (for which on June 18, 1914, I filed in Great Britain application No. 14688/14, published July 8, 1915, and sealed Sept. 2, 1915; and on June 12, 1915, filed application Serial No. 479,014 in France, said French application having been granted November 9, 1915, and published February 2, 1916), of which the following is a specification.'

The present invention relates to improvements in windows or the like, and concerns more particularly sliding windows.

In connection with railway carriages it has been proposed'to use plate lass windows which are not framed by a sas in the usual manner, but which slide directly in a window frame. There has been a diiculty, however,

in connection with such a construction inasmuch as the glass has a tendency to rattle, and various devices have been proposed to overcome this disadvantage, but these have not been entirely successful. It is an object of the present invention to provide means in which such a frameless or sashless window may slide easily without rattling, which means shall be chea and simple to manufacture and put in p ace.

According therefore to the present invention there is provided as a new article Yof manufacture a metal strip of channel-section combined with a lining of felt or like material attached thereto, by having an edge between a side wall of the lstrip and a tongue,

lip or the like which is preferably continuous, extending from the side wall and overhanging the edge of the lining and extending down over and into the marginal portion. of the lining.

A convenient construction according to the present invention will now be described with reference to the accompanying drawing which is a perspective view of a short len thof the aforesaid strip.

he strip A is of brass which is of channel-shape 1n cross-section and the inside of the channel is lined with felt B. In the manufacture of thestrip the upper margin. of the channel which is an upward continuation of the channel-sides is turned inwards and downwards -so that the lower part of the down-turned portion will overlie the top thickness of the channel side-walls and theirv inturned portions is such that the surface of the inturned portion is below the surface of the adjacent felt so that the window in sliding up and down will slide upon the felt and not upon the inturned metal.

In using such strip as a window frame in railway carria es, two long lengths of the strip are fixe to the panelling and are joined b a short strip at the top so that when the win ow is closed three of its edo'es will be in contact with the felt, which will tend to hold it in place. When the window is lowered its top edge will leave the cross strip, butv it will still be gripped bv the felt in the strips at the two sldes so that it will not rattle.

The invention h-as been described with reference to a frameless or sashless window, but is not limited thereto as it would also be useful in connection with a window having a sash. In this case, of course, the channel would have to be of wider section jin order to accommodate the thicker window ved e due to the sash.

urther a window sash itself might be formed of such strip, which would be joined together at the four corners in any convenient manner. In such a case the felt would prevent jars upon the frame from reaching the lass of the window. A window sashed in t is manner might be located in a window-frame formed of a strip according to the present invention.

Referencel has been made to windows used yin railway carriages, but the l. invention is equally useful in connection with sliding wlndows of motor cars, or other vehicles or of ships or in fact any sliding window, and in particular any sliding frameless or sashless window.

What I claim as my invention and to secure b Letters Patent is rIhe com ination of a metal strip of channel section having 4the ad'acent sides thereof extending atfsubstantially right angles to each other to form threev flat sides one of desire recess and the inner portion of said edge in abutting frictional engagement with the re-' spective shoulder, each side Wall of the lining extending to a plane inwardly of the respective shoulder, said lining being readily replaceable and disengageable from said channel member, and a glass sheet directly engaged by said lining.

In testimony whereof I 'alix my signature.

ARTHUR WATKINSON.
